Answer: Uniform Crime Reporting (UCR)
Explanation: The Uniform Crime Reporting is a program conducted by the FBI that presents crime data, based on reporting by agencies at the level of cities, universities, counties, states, and the federal level. It is a voluntary reporting of crimes, and there are around 18,000 agencies around the country. This program has been established by the FBI since 1930, and serves to monitor and analyse crime types. The primary objective of this monitoring and analysis is to collect data for use in law enforcement. Over the years, this data has become a significant statistical indicator of social trends in the country. Crime data from the UCR is used by different social structures and institutions and for different purposes. Thus, they are used by sociologists, criminologists, legislators, the media, urban planners, students, etc.
